the site wont copey the long adress(  http://speedtalk.com/forum/viewtopic.php?f=1&t=32279)

Tried that link, but it's not there.  Do you have it somewhere else?

Try this sitehttp://speedtalk.com/forum/viewtopic.php?f=&t=32279  be sure to read the whole artical.this paper takes all the old wives tales out of oil,also will save you some dollers. it proves diesel engine oils are a poor replacement for even the cheapest gas engine oils.

I've read that blog several times in the past, it's a lot to ingest, and some will believe it and some won't. Everyone will tell you something different about what oils to use so I won't add to the confusion. All I will suggest is spinning the pump to fill the filter and galleries first and bring the RPM up to 2500-3000, the cam depends on splash oil.. I broke my FE solid lifter motor in on Delo 15-40, running for 4 years with no problem. I used Shell Rotella T in my 292 and after 5,000 miles it's fine.

I guess 2 things that I took away from this article is: 1 - High levels of zinc do not necessarily equate to higher wear prevention, and 2 - The oils with the highest wear prevention properties are synthetic which everybody says you shouldn't run in a Y-block.  What do you folks think?

Use a good break in oil like Gibbs or Brad Penn.  These oils are "dinosaur based" with zinc and other additives to protect flat lifters and cam.  Stay away from synthetic oils until the rings have had a chance to properly seat (~5000 miles) and remember that older engine seals were not designed for this type of oil and may leak.

I'm getting closer to starting up my rebuilt 292 and have been reading up on the proper oil to use (maybe reading too much). I came across this article which goes into it in detail so great my head is spinning.  I know this is a subject that has been talked to death, but what kind of oil do you use and what do you think of the article's recomendations?
